NGG is an International Trading Company activating in Ferrous and Non- Ferrous Metals.

Ferrous Metals mostly contain Iron. They have small amounts of other metals or elements added, to give the required properties. Ferrous Metals are magnetic and give little resistance to corrosion.

Some examples of the ferrous metals are:

—Vehicle scrap metal

—Demolition Site scrap metal

—Metal offcuts from manufacturing industries

Non-Ferrous Metals do not contain Iron, are not magnetic and are usually more resistant to corrosion than ferrous metals.

Some examples of Non-Ferrous Metals are:

—Copper

—Lead

—Stainless Steel

Stainless Steel Coils /Sheets

Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the  passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.

Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance.

Stainless Steel Scrap

Stainless steel scrap contain valuable raw materials like nickel and chromium and that makes its recycling economically viable. The metal is economically recycled on a large scale across the world by recyclers who collect and process stainless steel scrap for remelting.

Stainless Steel Alloy Scrap is fundamental to the process of steel making. The two basic types of scraps include :

—Reclaimed scrap (old scrap) – It includes industrial equipment, tanks, washing machines and refrigerators, which have reached the end of their usage life.

—Industrial scrap (new scrap) – Industrial scrap includes production offcuts or industrial returns from manufacturing by industrial engineering and fabrication sources.

Tin ingots

Commercial grades of tin (99.8%) resist transformation because of the inhibiting effect of the small amounts of bismuth, antimony, lead, and silver present as impurities. Alloying elements such as copper, antimony, bismuth, cadmium, and silver increase its hardness. Tin tends rather easily to form hard, brittle intermetallic phases, which are often undesirable. It does not form wide solid solution ranges in other metals in general, and there are few elements that have appreciable solid solubility in tin. Simple eutectic systems, however, occur with bismuth, gallium, lead, thallium, and zinc.

Tin ingots with a purity of 99.85%. The net weight of each billet is 25 kg and the dimensions are 40 * 12 in width and 5 cm in thickness.

Lead Ingots

Lead is used in building construction, lead-acid batteries, bullets and shots, weights, as part of solders, pewters, fusible alloys and as a radiation shield. Lead has the highest atomic number of all of the stable elements, although the next higher element, bismuth, has a half-life that is so long (much longer than the age of the universe) that it can be considered stable. Its four stable isotopes have 82 protons, a magic number in the nuclear shell model of atomic nuclei.
